Hello ProxMox community

I am running ProxMox VE 7.1 on the computer below

Dell - Inspiron 3880 Desktop

10th Gen Intel® Core™ i7-10700

Intel UHD Graphics 630

The Issue I am facing


I have these steps to enable IOMMU

1. added the line "GRUB_CMDLINE_LINUX_DEFAULT"="quiet intel_iommu=on" to /etc/default/grub

2. added the following to /etc/modules

vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd

Possible Issue
The intel processor supports VT-D. When I enabled it in the BIOS I saw in the text description, it shows the trusted execution needs to be activated. Does anyone have experience with this? Do I need to TPM for this to be enabled on my Dell Desktop?
